In general TWiki is good about preserving form field entry in the event of the user backing up.

BlogPlugin (at least in my install) lost the submission.

Does this do this elsewhere?

Thanks, Martin.

Wbniv reported the same thing and I made the same painful experience just recently after typing for nearly an hour frown .

This is not related to the BlogPlugin. The only thing that I can do is to remove as many of the mandatory flags as possible.

So which are the circumstances that come together in the BlogPlugin when creating a new posting? Here is the form to create a new posting:

<form action="%SCRIPTURL{"edit"}%/%WEB%/BlogEntryXXXXXXXXXX" method="post">
<input type="hidden" name="onlywikiname" value="on" />
<input type="hidden" name="templatetopic" value="BlogEntryTemplate" />
<input type="hidden" name="formtemplate" value="BlogEntryForm" />
<input type="hidden" name="topicparent" value="WebHome" />
<input type="hidden" name="topic" value="BlogEntryXXXXXXXXXX" />
<input type="hidden" name="BlogAuthor" value="%WIKINAME%" />
<input type="hidden" name="TopicType" value="%TOPIC%" />
<input type="hidden" name="TopicDescription" value="" />
<input type="hidden" name="action" value="form" />
<input type="hidden" name="Date" value="%SERVERTIME%" />
<input type="submit" class="blogSubmitButton" value="New Posting" />

Both, templatetopic and formtemplate settings, get lost clicking on back.

This needs further investigation to check the issue on a simpler setup.

Besides this error I would suggest to improve the workflow in the case a mandatory field is empty: redirect to edit right away and highlight the missing bit with an appropriate message instead to insist that the user should go back in his browser. That's what other webapps do.

Recasting it to "Engine" and "Urgent".

-- MD.

Here's what I tried:

| *Name:*| *Type:* | *Size:* | *Values:* | *Tooltip message:* | *Attributes* |
| Text | text | 50 |  a,b,c,d | Arfle | |
| MText | text | 50 |  a,b,c,d | Barfle | M |
In a topic, created this form:
<form action="%SCRIPTURL{"edit"}%/%WEB%/TestThreeXXXXXXXXXX" method="post">
Text: <input type="text" name="Text" />%BR%
MText: <input type="text" name="MText" />%BR%
formtemplate <input type="text" name="formtemplate" value="TestForm" />%BR%
<input type="submit" />
Typed in something to the Text field, left MText blank, hit submit. Got a mandatory field exception, so I hit back; and the correct value of Text was still there. Also tried with save instead of edit. This works as expected, so I'm bouncing this back to the BlogPlugin until it can be demonstrated on the engine with a testcase. See MandatoryTestTopic


I think I saw this/similar behaviour only once or twice with Firefox. In both cases some time passed (30 mins+) from the loading of the page till the submit, and other tabs were used to browse the site in between.

I think there is nothing in the headers suggesting any timeconstraints, so I know this observation is not that helpful; just wanted to note it anyway.

Crasy idea: Perhaps this could be related to the internal cache mechanism in browser (submit page gets "swapped out" after some period)?

-- SP

I think SP is right. The page just displayed has been displaced from cache and is not added back again when visiting another... a thing that can't be fixed from within the BlogPlugin extension. The recent BlogPlugin releases removed the "mandatory" field almost all formfields despite those that can be set automatically.

Ponging this item back to "engine".


Shame we don't have a "not our fault" status. I'm pretty much convinced wthis is a browser problem, and there's nothing TWiki can do about it. If someone can produce a testcase that proves otherwise, please go ahead and re-open it.
